Inventory X Mod 1.12.2/1.11.2/1.10.2 (Button to Close Inventories)

Inventory X Mod1.12.2 is a convenient mod that aims to add a little X button to the top right corner of inventories in Minecraft. The benefit of this button is that you can click it to close the inventory quickly, instead of pressing E or Escape like before.

Note that this is a feature in the Windows 10 edition of the game. The mod is compatible with client side, it means that even it is not installed on the server you are playing on, it still works well.
